HOSE OR PIPE CLEANING APPLIANCE.

SPECIFICATION forming part of Letters Patent No. 618,051, dated January24, 1899.

Application filed February 9, 1898. Serial No. 669,703. (No model.)

T0 (0% whom it may concern:

Be it known that we, JAMES S. BOWMAN and \VILLIAM E. GRAHAM, citizens ofthe United States residing at Cleveland, in the county of Cuyahoga-andState of Ohio, have invented a certain new and useful Hose or PipeCleaningApplian ce,of which the following is a specification.

Our invention consists in the construction of a cook or valve adaptedfor use in connection with other suitable means (brushes) for thepurposev of cleaning (scrubbing) the in terior of hose, pipes, (to.

That the invention may be fully seen and understood, reference will behad to the following specification and accompanying drawings, in whichFigure 1 represents a horizontal sectional view of said cock or valve online X X, Fig. 3. Fig. 2 illustrates another sectional view on line X X,Fig. 3. Fig. 3 is avertical longitudinal sectional View on line Y Y,Fig. 1; and Fig. at is a vertical transverse sectional view on line Z Z,Fig. 1.

Like letters of reference denote like parts in the drawings andspecification.

Substantially the contrivance consists of a peculiar branch cock, ofwhich two branches are arranged in central alinement, while the third isoffset or in a different plane and projecting in about a rightangledirection to the first-mentioned branches.

The casing A or body part of the cook comprises the conical sleeve a andthe branches 1), c, and d. Preferably the terminal of the branch Z) isthreaded externally for a coupling connection, as seen at 6, while thebranch cl is adapted for pipe connection, as seen at f. (See Figs. 1, 2,and 3.)

The plug B is fitted to the conical sleeve (0 and retained in operativeconnection with the casing A by means of the washer g and the nut h,which screws upon the shank i of the small end of said plug. (See Fig.8.) The large end of the plug has a suitable projection j to enablemanipulation of said plug.

The plug proper is of the hollow type. Side openings are formed at 7.;and Z, which establish either an open relation of the branches b c orthe branches 1) and (Z.

Shown in Fig. 1 is an open relation of or between the branches 1) 0,established by the lateral port K, and the branch d is shut out. Aquarter-turn of the plug in direction of the arrow shuts outcommunication of the branch 0. The port Z then will register with branchd, and by way of the cavity of the plug communication is attainedbetween the branches d and Z). A cook or valve so con structed becomes apreeminently useful element in the mode or work of cleaning the in= sideof hose or pipes, &c., in conjunction with the application of brushes orscrapers.

For freeing the inside of hose, pipes, 850., in an efficient andthorough manner from objectionable or detrimental deposits brushes orthe like must necessarily be used for scrub bing the interior wallsthereof. Also the ap plication of a suitable liquid solvent becomesdesirable aside from the use of water. It can readily be seen that wesupply a means suited for the nature of such work in the above-describedcontrivance, since the same can be used in the following manner:

The branch cl is connected with any suitable water-supply pipe, whileonto the branch I) is coupled the hose or pipe requiring cleaning. Bysetting the plug as indicated in Fig. l the water-supply is shut off,while the branches b and 0 remain in open relation one with the other,owing to the position of the lateral port K. A brush or other suitablearticle can thus be inserted into the branch I) by way of the auxiliarybranch 0. After placing the brush a quarter-turn of the plug suffices toclose branch 0 and to open branch d, whereupon the water rushes upon thebrush and drives same through the hose or pipe attached for beingscrubbed and cleaned.

An additional pipe connection can be had with branch I) at m for thepurpose of introducing soapsuds or the like into the pipe either before,with, or after the chasing of the brush through said pipe. The lineararrangement of the branches 1) and c admits the use of comparativelylong brushes equally well as short brushes; but evidently with longbrushes the work can be accomplished more thoroughly.

What we claim, and desire to secure by Letters Patent of the UnitedStates, is-- In a hose-cleaning appliance enabling the manipulation ofcylindrical brushes, a cock I) all constructed and arrangedsubstantially consisting of a casing with conical sleeve a as and forthe purpose set forth.
